1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

purposePlate-clearing behavior (PCB), a maladaptive behavior in a food environment characterized by large, energy-dense portions of food, may contribute to weight gain over time. If a portion size is selected that causes overeating, a trade-off exists between food waste and weight gain due to PCB. However, patterns between PCBs and pre-meal portion planning to prevent overeating (PPP-O) remain overlooked. This study aimed to identify these patterns in various meal situations and describe the demographic, anthropometric, psychological, and lifestyle-related characteristics of those following each pattern.

methodsOverall, 1,707 Japanese participants responded to a web-based anonymous questionnaire in February 2023. Cluster analysis was performed to identify patterns in PPP-O and PCB. Multiple logistic regression analysis was used on clusters of participant characteristic variables.

resultsThe median age of the participants was 40 (25th and 75th percentile: 30, 50) years (female = 865, 50.7%). Four clusters with independent predictors were identified: low PPP-O and high PCB, moderate PPP-O and high PCB, moderate PPP-O and low PCB, and high PPP-O and low PCB. Low BMI and a higher positive attitude toward food waste were independent predictors in high PPP-O and low PCB, while high BMI was an independent predictor in moderate PPP-O and high PCBs and low attitude toward food waste were independent predictors in moderate PPP-O and low PCB. Psychological factors were described as independent predictors of several clusters.

conclusionThe results support the possibility of a trade-off between food waste and weight gain if PPP-O is not implemented.
